/readonly
Prove, don't guess. Investigate with every read-only source that can answer the question, then stop before changing anything.
This is a user-invoked modifier. Use it when the user explicitly writes /readonly, including beside another skill name.
Core rule
When /readonly is present, treat every other instruction or invoked skill as diagnostic only. Run its reading, tracing, classification, and reasoning steps, but skip any step that edits files, opens issues, changes configuration, creates branches, commits, pushes, posts comments, deploys, installs, regenerates, or otherwise mutates local or remote state.
